firewire: add KUnit test to check layout of UAPI structures

2023-05-29T23:12:39+00:00

In future commits, some new structure will be added to express new type of event. They are exposed to user space as the part of UAPI. It is likely to get trouble in ioctl compatibility layer for 32 bit binaries in 64 bit host machine since the layout of structure could differ depending on System V ABI for these architectures. Actually the subsystem already got such trouble at v2.6.27. It is preferable to decide the layout of structure carefully so that the layer is free from such trouble. This commit utilizes KUnit framework to check the layout of structure for the purpose. A test is added for the existent issue.

firewire: Remove depends on HAS_DMA in case of platform dependency

2018-12-03T17:45:14+00:00

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Signed-off-by: Geert Uytterhoeven Reviewed-by: Mark Brown Acked-by: Robin Murphy Signed-off-by: Stefan Richter

firewire: IEEE 1394 (FireWire) support should depend on HAS_DMA

2014-07-13T18:53:25+00:00

Commit b3d681a4fc108f9653bbb44e4f4e72db2b8a5734 ("firewire: Use COMPILE_TEST for build testing") added COMPILE_TEST as an alternative dependency for the purpose of build testing the firewire core. However, this bypasses all other implicit dependencies assumed by PCI, like HAS_DMA.

firewire: ohci: move runtime debug facility out of #ifdef

2012-03-10T16:41:19+00:00

CONFIG_FIREWIRE_OHCI_DEBUG could have been exposed to kernel tweakers if CONFIG_EXPERT was set. But in hindsight, this stuff is far too useful to omit it. So get rid of two #else branches that are only going to bitrot otherwise. Signed-off-by: Stefan Richter
